Tub and shower surrounds are great for eliminating the need for grout and tile. They are constructed of solid sheets which are put together on site, and many of the higher-end models feature storage shelves. The solid design eliminates mold and mildew build up. Typically the highest grade is made of acrylic material, and lower grades are constructed of gelcoat and fiberglass. Tub and shower surrounds can be installed over existing condition to cover old tile, or they can be installed unto a stud wall. Be sure to check installation instructions prior to placing your order.
